If you only want buttons you might try:

require 'tk'
  #= windowmaker - create button array, each pops a window
  #global $button[] holds buttons defined by this method
  #parm root    the frame which is to hold the button
  #parm b_text  the button text; also becomes toplevel title
  #parm t_place String, "0x0+100+200", toplevel window size, place
  #parm init_color String, "#000000", 2 hex digits for red, green, blue
  #
  def windowmaker(root,b_text,t_place,init_color="#000000")
    toplevelwindow = -1
    b = TkButton.new(root,
      'text'=>b_text,
      'command'=> proc {
          toplevelwindow = TkToplevel.new(root, {
            'title'=> "#{b.text}",
            'geometry'=>t_place,
            'bg'=>init_color
          })
      }
    ).pack('expand'=>'yes','fill'=>'x')
    $buttons.push [b,toplevelwindow]
  end

r = TkRoot.new
f = TkFrame.new(r)
$buttons = [] # each entry holds [button,toplevel]
windowmaker(f,"red","100x100","#ff0000")
windowmaker(f,"white","200x200","#ffffff")
windowmaker(f,"blue","300x300","#0000ff")
windowmaker(f,"0x400+100+100","dummy") # re-configured:
# show reconfiguration of the last button
$buttons[-1][0].configure('command'=>proc{r.destroy;
exit},'text'=>"Quit")
f.pack
Tk.mainloop
